Abstract

A method and system for oxygen molecule scavenging is disclosed. The system employs as an amphiphilic dendritic polymer as the reducing agent for oxygen molecules in a thermoplastic compound. Clarity of the compound, nearly the same as thermoplastic matrix itself in the compound, is achieved by the addition of an epoxy-functional styrene-acrylate oligomer. Food and beverage containers now made of polyethylene terephthalate can be molded from the compound and have substantially the same haze as the polyethylene terephthalate itself but with the oxygen scavenger to maintain freshness of the food or beverage from oxidation.
